Dry contacts
Intrinsically safe input signals
One 4-wire Coriolis sensor signal input with ground
Non-intrinsically safe output signals
Two active
4–20 mA outputs Isolated to ±50 VDC from all other outputs and earth ground
Maximum load limit of 1000 Ohms
Output is linear with process from 3.8 to 20.5 mA per NAMUR NE43 (June 1994)
Three discrete outputs Configurable for the application
Polarity Active high or active low, software selectable
Power Internal pull-up to 24 V
Voltage 24 VDC nominal
Current Sourcing at 5.6 mA when V
out
= 3 VDC
Sinking up to 500 mA at 30 VDC maximum
One 2-wire
frequency/pulse output Scalable to 10,000 Hz
Output is linear with flow rate to 12,500 Hz
Pulse width 50% duty cycle above the crossover frequency (1)
(1) The crossover frequency depends on the configured value of the pulse width. At the minimum pulse width value of 0.543 ms, the
crossover frequency is 922 Hz. At the maximum pulse width value of 277 ms, the crossover frequency is 1.8 Hz.
Configurable between 0.543 ms and 277 ms
Polarity Active high or active low, software selectable
Power Active or passive, software selectable
Voltage 24 VDC nominal, active
30 VDC applied maximum, passive
Current Sourcing at 10 mA at 3 VDC, active
Sinking at 500 mA, active or passive
